It's the Seattle Supersonics' team card from the 1975-'76 Topps basketball set.
I like the idea of having the team stand in front of an airplane since they're named after one. However, they didn't stand in front of a Supersonic plane like the Concorde, it's a 747. However, the company that manufactured the 747 was Boeing, a company that was founded in Seattle. So, there was a "hometown" angle behind the picture.
